    A typical example of plants that are not rooted and free to move about the surface of the water is  - ProProfs

    A typical example of plants that are not rooted and free to move about the surface of the water is 

    • Nelumbo nucifera

    • Nymphaea alba

    • Liverworts

    • Duck weed

    Correct Answer
    A. Duck weed
    Explanation
    Duckweed is a typical example of plants that are not rooted and free to move about the surface of the water. Duckweed is a small floating plant that is often found in ponds and other bodies of water. It has no roots and instead floats freely on the surface, allowing it to move with the water currents. This adaptability allows duckweed to quickly colonize new areas and spread across bodies of water.

    A group of  underwater plants that can survive both under the water and on the land are termed - ProProfs

    A group of  underwater plants that can survive both under the water and on the land are termed

    • Helophytes

    • Pleutons

    • Macrophytes

    • Ampiphytes

    Correct Answer
    A. Ampiphytes
    Explanation
    Amphiphytes are a group of underwater plants that have the ability to survive both under the water and on land. They are adapted to live in both aquatic and terrestrial environments, allowing them to thrive in areas that experience fluctuations in water levels. These plants have specialized structures that enable them to obtain oxygen and nutrients from both water and soil. By being able to survive in both habitats, amphiphytes have a greater chance of survival and are able to colonize a wider range of ecosystems.

    Underwater plants are known to survive exclusively on - ProProfs

    Underwater plants are known to survive exclusively on

    • Arid lands

    • Wetlands

    • Islands

    • Thick lands

    Correct Answer
    A. Wetlands
    Explanation
    Underwater plants are known to survive exclusively in wetlands. Wetlands provide the necessary conditions for these plants to thrive, such as a constant water supply and nutrient-rich soil. Arid lands, islands, and thick lands do not typically have the required moisture levels and conditions for underwater plants to survive. Therefore, wetlands are the correct answer in this case.

    The most common adaptation of underwater plants is - ProProfs

    The most common adaptation of underwater plants is

    • Parenchyma

    • Collenchyma

    • Tap root

    • Aerenchyma

    Correct Answer
    A. Aerenchyma
    Explanation
    Underwater plants often face the challenge of obtaining oxygen for respiration. Aerenchyma is a specialized tissue that helps these plants adapt to their aquatic environment by providing a pathway for the exchange of gases. It consists of large air-filled spaces within the plant's tissues, allowing for the diffusion of oxygen from the atmosphere to reach the submerged parts of the plant. This adaptation enables underwater plants to survive and thrive in low-oxygen environments, making aerenchyma the most common adaptation among them.

    Since seaweeds are multicellular marine algae and avascular, they are not - ProProfs

    Since seaweeds are multicellular marine algae and avascular, they are not

    • Isoetids

    • Elodeids

    • Aquatic plants

    • Nymphaeids

    Correct Answer
    A. Aquatic plants
    Explanation
    Seaweeds are classified as aquatic plants because they are multicellular marine algae that grow in water. Although they are not vascular plants, they still share similarities with other aquatic plants in terms of their habitat and growth patterns. Seaweeds are able to photosynthesize and obtain nutrients from the water, just like other aquatic plants. Therefore, the correct answer is aquatic plants.

    Among others, an example of aquatic plants consumed by humans is - ProProfs

    Among others, an example of aquatic plants consumed by humans is

    • Thalassia

    • Ceratophyllum submersum

    • Zostera

    • Ipomea aquantica

    Correct Answer
    A. Ipomea aquantica
    Explanation
    Ipomea aquantica is an example of an aquatic plant that is consumed by humans. This plant, also known as water spinach or kangkong, is a popular leafy vegetable in many Asian cuisines. It is rich in vitamins and minerals, and its tender shoots and leaves are commonly used in stir-fries, soups, and salads. Due to its high nutritional value and versatility in cooking, Ipomea aquantica is widely consumed and enjoyed by people around the world.

    The concentration of underwater plants decrease with the depth of the water, as a  result of the - ProProfs

    The concentration of underwater plants decrease with the depth of the water, as a  result of the

    • High salt concentration

    • Sea waves

    • Minimal sunlight

    • Numerous predators

    Correct Answer
    A. Sea waves
    Explanation
    Sea waves can cause turbulence and disturbance in the water, which can affect the growth and stability of underwater plants. Strong waves can uproot or break the plants, leading to a decrease in their concentration. Additionally, waves can stir up sediments and increase water turbidity, reducing the amount of sunlight available for photosynthesis. This can further hinder the growth of underwater plants and contribute to their decreased concentration with increasing depth.

    The principal factor that control the distribution of underwater plant is - ProProfs

    The principal factor that control the distribution of underwater plant is

    • Salinity

    • Grazing

    • Flooding

    • Abundance

    Correct Answer
    A. Flooding
    Explanation
    Flooding is the principal factor that controls the distribution of underwater plants. Flooding can determine the availability of water and nutrients in an area, which directly affects the growth and survival of underwater plants. It can also impact the amount of light that reaches the plants, as excessive flooding can lead to increased turbidity and reduced light penetration. Therefore, flooding plays a crucial role in shaping the distribution patterns of underwater plants.

    A group of rosette plants which completes its entire lifecycle while submerged in water are called - ProProfs

    A group of rosette plants which completes its entire lifecycle while submerged in water are called

    • Pleuston

    • Liverworts

    • Bladderworts

    • Isoetids

    Correct Answer
    A. Isoetids
    Explanation
    Isoetids are a group of rosette plants that are able to complete their entire lifecycle while submerged in water. This means that they are adapted to live and reproduce in aquatic environments. Unlike pleuston, which refers to organisms that live on the surface of water, isoetids are specifically adapted to live underwater. Liverworts and bladderworts are not specifically known for completing their lifecycle underwater, making isoetids the correct answer.
